Two Delta Air Lines flight attendants are alleging that wearing their uniforms causes skin rashes, headaches, fatigue and other issues in a proposed class-action lawsuit filed Wednesday.

The "Passport Plum" uniforms were made by Lands' End, a global fashion retailer, and issued to 64,000 employees in May 2018, according to the lawsuit. Land's End is named as a defendant in the lawsuit; Delta is not.

The suit seeks more than $5 million in damages and was filed in U.S. District Court in the Southern District of New York by flight attendants Gwyneth Gilbert and Monica DeCrescentis. Gilbert lives in Sandy Springs, Georgia, and alleges in the lawsuit that she experienced rashes and skin irritations from wearing the uniforms, which consisted of two dresses, a pantsuit and a sweater set.

DeCrescentis, from New York alleges in the suit that she experienced skin reactions, headaches and a low white cell blood count over the past year since she has been wearing the uniform. She also alleged that the dye in the clothing transferred onto her body, sheets, clothes and bathtub.

Lands’ End told USA TODAY that it does not comment on pending litigation.

The lawsuit states that because Delta flight attendants are non-union, many flight attendants are afraid to complain about the adverse health consequences they are experiencing from uniforms.

Although Delta is not named in the suit, the airline issued a statement on its uniforms: "Although Delta and Lands’ End conducted in-depth testing during every step of development, a small number of employees have reported skin irritations.

"While less than one percent of employees in the new uniform program have reported issues, Delta takes this very seriously and is working directly with employees on solutions that meet their individual needs."

The lawsuit alleges that Lands' End was negligent in failing to use reasonable care in designing, manufacturing, marketing, labeling and selling the uniforms.

The outfits were created by New York fashion designer Zac Posen. The outfits were rolled out with much fanfare in 2018, more than a year after the new threads were first unveiled in the fall of 2016 after "extensive testing" to make sure they would perform as expected.
